Short packets with FBL codes are considered to reduce the transmission delay and support low-latency communication. In the FBL regime communication, in contrast to Shannon's capacity for infinite blocklength, decoding error probability at the receiver is not negligible owing to short blocklength [1]}. Polyanskiy et al. succeeded in deriving an exact approximation of the FBL regime’s information rate at the AWGN channel [2]}. Following that, research in this context developed to MIMO channel with quasi-static fading [3]} and a quasi-static fading channel with retransmissions [4]}. Furthermore, the effect of short packets on the spectrum sharing, and scheduling of delay-sensitive packets was considered in [5]} and [6]}, respectively. In [7]}, massive MIMO adoption to maximize the achievable uplink data rate for industrial applications was advocated for both MRC and zero-forcing (ZF) receivers. In [8]}, the resource allocation for a secure mission-critical IoT communication system was studied under finite blocklength, and two optimization problems with the aim of weighted throughput maximization and total transmit power minimization were addressed. The authors in [9]} proposed a cross-layer framework for optimizing user association, packet offloading rates, and bandwidth allocation for mission-critical IoT scenarios.
